United States v. Nieves-Diaz, No. 21-1519 (1st Cir. 2024)
Annotate this Case
The defendant, Heclouis Nieves-Díaz, was on supervised release for a federal drug conviction when he was convicted of possession of ammunition as a convicted felon, illegal possession of a machine gun, and possession with intent to distribute cocaine. He received an 84-month prison term for each conviction, to be served concurrently. His supervised release was also revoked, resulting in an additional 18-month prison term to be served consecutively to his 84-month sentences.
Nieves had previously pleaded guilty to one count of drug conspiracy and was sentenced to 80 months of imprisonment and 96 months of supervised release. His term of supervised release was twice revoked. While on his third term of supervised release, Nieves was arrested following a search of an apartment where he was residing. The search yielded cocaine, marijuana, approximately 149 rounds of .223 caliber ammunition, and a device that could convert a Glock pistol into a fully automatic weapon.
Nieves appealed his 84-month sentences and the revocation sentence. He argued that the District Court improperly calculated his Guidelines Sentencing Range (GSR) for each of the underlying offenses and that the court's application of a four-level enhancement was incorrect.
The United States Court of Appeals for the First Circuit found that the District Court did err in applying the four-level enhancement, as the record did not support the determination that the ammunition in this case had the required potentially facilitative effect. Therefore, the court vacated the District Court's sentences and remanded for resentencing. However, the court affirmed the revocation sentence, finding it both procedurally and substantively reasonable.
